Scala SortedMap drop() method with example
The drop() method is utilized to delete the first ‘n’ elements.
Method Definition: def drop(n: Int): SortedMap[A, B]
Return Type: It returns all the elements of the SortedMap except the first ‘n’ elements.
Example #1:
// Scala program of drop() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a SortedMap val m 1 = SortedMap( "Beginner" - > 5 , "for" - > 3 , "cs" - > 5 ) // Applying drop method val result = m 1 .drop( 1 ) // Displays output println(result) } } |
Output:
Map(for -> 3, Beginner -> 5)
Example #2:
// Scala program of drop() // method import scala.collection.immutable.SortedMap // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a SortedMap val m 1 = SortedMap( "Beginner" - > 5 , "for" - > 3 , "Beginner" - > 5 ) // Applying drop method val result = m 1 .drop( 1 ) // Displays output println(result) } } |
Output:
Map(Beginner -> 5)
So, both the identical keys are removed from the SortedMap.
